Aecon sells its investment in Churchill Corporation09:43 EST Monday, November 22, 2010TORONTO, Nov. 22 /CNW/ - Aecon Group Inc. (TSX: ARE) announced today that it has sold all of the common shares it acquired earlier this year in Churchill Corporation ("Churchill"), resulting in net proceeds, after costs, of $60.8 million and a pre-tax gain of approximately $2 million.On June 15, 2010 Aecon announced that it had purchased 3,056,000 subscription receipts offered by Churchill, which it subsequently converted to common shares. Including additional shares purchased through The Toronto Stock Exchange, Aecon acquired a total of 3,513,600 common shares, or approximately 14.7 percentof the outstanding common shares of Churchill."We made this investment because we saw good value in a company and sector we know well, and because we saw an opportunity to explore areas of mutual interest," said John M. Beck, Aecon's Chairman and Chief Executive Officer. "Since that time, the significant progress we have made in merging Aecon Buildings into our Infrastructure operations, and the expansion of our core business in Western Canada to include mining have diminished the rationale for exploring further strategic alignment with Churchill. Disposing of our stake in Churchill allows us to continue to focus on the fundamentals of our business, including the continuing integration of our Buildings and Infrastructure businesses, establishing Aecon Mining, and strong project execution."
